Many of the students of the high school in Jokela, the site of last November's school shooting, are at risk of suffering from post-traumatic stress disorder, or PTSD. Researchers concluded that nearly half of girls and a fourth of boys have an elevated risk of developing PTSD.
According to the ongoing two-year study into the students' wellbeing conducted by the National Public Health Institute, most of the students exhibited some symptoms of trauma directly after the tragedy.
Nine people were killed when an 18-year-old boy opened fire in his high school before turning the gun on himself.
The study showed that students affected by the Jokela tragedy found solace foremost through their family and friends, especially right after the events. They were also grateful for the easy availability of crisis workers.
The National Public Health Institute believes that the media may have increased the risk of PTSD in some students by interviewing them. One in ten students, however, said they felt better after having talked about the events with reporters.
